Crucial factor: human. Safely extending the human presence in space

Abstract:
The concept of advanced manned space missions has captured the interest and imagination of spacefaring nations. However, the physiological and psychological effects of space flight increase in magnitude and significance in the 'extended time-in-space' context. The unencumbered weightless condition enjoyed during short flights might compromise crew productivity upon return to a gravity field and extremely effective countermeasures may be essential. Missions remote from Earth require careful consideration of the medical facilities, psychological support and life support needed. The author discusses pressing issues that must be resolved before the visions of bolder human missions can be realistically fulfilled.
